Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture cages, and in particular to an aquaculture cage which is convenient for fishing and harvesting. Background Art

[0002] 70.8% of the earth's surface is covered by the vast ocean, and the marine resources are very rich. Marine aquaculture can use marine resources to breed other economic animals such as fish, shrimp, shellfish, etc., and improve the utilization rate of marine resources. At present, when conducting marine aquaculture, most of them adopt a lifting cage structure, put the young economic animals such as fish fry and shrimp fry into the aquaculture cage, sink the aquaculture cage into the sea, and complete the breeding of the young in the aquaculture cage. For example, an existing lifting and rotating marine fish aquaculture cage and its use method include a structural float, a farming cage body, a lifting mechanism and a rotating mechanism; the structural float floats on the water surface, a hanger is provided on the structural float, and the lifting mechanism is arranged on the hanger. The lifting mechanism is connected to the farming cage body, and the farming cage body is lifted / lowered relative to the structural float through the lifting mechanism; the surface of the farming cage body is covered with a fishing net; the rotating mechanism is arranged on the structural float and connected to the farming cage body, so that the farming cage body is in a descending state to realize the rotation of the farming cage body to dry the net. This solution enables the cage to be raised, lowered and rotated, reduces the cage's draft, and solves the problems of cage hauling, docking for maintenance, and catching adult fish.

[0003] However, when fishing and collecting, the aquaculture cages in this solution can only partially peel off the fishing net on the surface of the cages, so that a discharge port for aquatic products appears on the upper surface of the cages. It is difficult to quickly take out the aquatic products in the aquaculture cages through the discharge port. If the taking out time is too long, it is easy to cause the death of aquatic products, which further increases the cost loss. Utility Model Content

[0004] The utility model solves the problem that it is difficult to quickly take out the aquatic products in the net cage in the above-mentioned prior art solutions when fishing and harvesting, and provides a breeding net cage that is convenient for fishing and harvesting. The mesh on the breeding net cage in this solution can be unfolded, and the aquatic products in the breeding net cage can be quickly taken out after the net cage is unfolded.

[0005] The technical solution adopted by the utility model is: a breeding cage that is convenient for fishing and harvesting, including a floating platform, a lifting mechanism fixedly connected to the floating platform, a rotating mechanism fixedly connected to the driving end of the lifting mechanism, and a cage connected to the driving end of the rotating mechanism. The floating platform is provided with a lifting port, and the cage can pass through the lifting port to enter the sea. The cage includes a regular polygonal side panel and a mesh group that is unfolded into a rectangle. The rotating mechanism is connected to the side panel, the side panel constitutes the two end faces of the cage, the mesh group constitutes the side of the cage, the rotating mechanism is a rotating motor, and the driving end of the rotating motor is connected to the center line of the side panel. The mesh group includes a plurality of meshes that are connected to rotate in sequence, and two adjacent meshes are connected by a rotating shaft. One end of the mesh connected to the side panel is provided with a first fixing portion for connecting to the side panel, wherein each mesh corresponds to an edge of the side panel, and the first fixing portion can fix the mesh and the side panel together. The two meshes at both ends of the mesh group are provided with guide rods, the guide rods are located at one end of the mesh away from the rotating shaft, the floating platform is provided with an electric slide rail, the electric slide rail is slidably connected with an electric slider, the electric slider is provided with a slot, and both ends of the guide rods are provided with ball heads that can be inserted into the slot. Specifically, the two meshes at both ends of the mesh group are driving meshes, the guide rods are located at one end of the driving mesh away from the rotating shaft, the two ends of the guide rods are provided with telescopic rods, the ball heads are connected to the guide rods through the telescopic rods, and the telescopic rods can extend the ball heads into the slots of the electric slider, the floating platform is also provided with a power mold base electrically connected to the electric slider, the power mold base provides power to the electric slider, a pulley is provided at the bottom of the electric slider, and the electric slider slides in the electric slide rail by rotating the driving pulley.

[0006] When the farmed fish in the farming net cage are caught, the lifting mechanism drives the net cage below the sea level to move upward until the net cage floats out of the sea level, and then rotates the net cage so that the guide rod on the net cage is the highest point of the net cage in the vertical direction. When the net cage floats out of the water, it will pass through the lifting port on the floating platform. At this time, the telescopic rods at both ends of the guide rod shrink, and the ball head on the guide rod passes through the floating platform and aligns with the slot on the electric slider, and then the ball head on the guide rod extends into the slot. At the same time, the lifting mechanism continues to drive the net cage to rise. After the ball head is stuck in the slot, the electric slider slides in the electric slide rail in the direction away from the net cage, so that the driving mesh has a tendency to unfold. At this time, the first fixing part on the driving mesh is opened, and the driving mesh rotates on the rotating shaft until the driving mesh is unfolded on the floating platform. Similarly, the electric slider continues to move to drive more mesh to unfold on the floating platform until the range of the mesh on the farming net cage is large enough. At this time, all the unfolded meshes in the mesh group are spread flat on the surface of the floating platform, and the farmed fish in the net cage can be caught through the unfolded part in the net cage. When the aquaculture cage is relocated, the lifting mechanism drives the cage downward, and the electric slider also moves in the direction of the cage. At this time, the electric slider will drive the unfolded mesh to re-engage with the side of the side panel. When the mesh abuts against the side panel, the first fixing part on the mesh completes the connection between the mesh and the side panel frame, so that the mesh is fixed on the side panel until all the meshes are fixed on the side panel. At this time, the inner cavity of the cage is in a closed state. Then the ball head on the guide rod is disengaged from the slot on the electric slider, and the lifting mechanism continues to drive the cage down, and the cage sinks back into the sea to complete the relocation of the cage. When the net on the mesh needs to be cleaned, all the meshes are unfolded on the floating platform so that all the nets on the cage can be effectively cleaned.

[0007] When the aquatic products inside the aquaculture cage in this scheme need to be taken out, the mesh on the side wall of the cage can be unfolded and spread flat on the floating platform, and a gap sufficient for fishing is opened on the cage, so that the staff can quickly take out the aquatic products in the cage through the gap on the cage, shortening the fishing time of farmed fish and avoiding the death of too many farmed fish due to the long fishing process. At the same time, the mesh can be fully unfolded on the floating platform, and the working space is larger when cleaning the net on the mesh, which is more convenient for the staff to clean and replace the net.

[0008] Preferably, the first fixing part includes a first fixing seat, a first hydraulic rod and a first fixing plate, the first fixing seat is C-shaped, the end of the first fixing plate is rotatably connected to the inner cavity of the first fixing seat, one side of the first fixing plate is fixedly connected to the frame of the mesh, and the other side is rotatably connected to the first hydraulic rod, and the other end of the first hydraulic rod is rotatably connected to the inner cavity of the first fixing seat. The extension of the first hydraulic rod will drive the first fixing seat to rotate on the mesh, and when the first hydraulic rod is extended to the first fixing plate and the bottom surface of the first fixing seat is perpendicular, a limiting groove for accommodating the side panel frame will be formed between the mesh and the first fixing seat, and the side panel frame can be fixedly connected to the mesh after being inserted into the limiting groove. The specific working principle is as follows: when the mesh is connected to the side panel, the first hydraulic rod is extended, so that the opening of the limiting groove becomes larger, and after the side panel frame enters the inner cavity of the limiting groove, the first hydraulic rod is contracted, so that the limiting groove becomes smaller, until the side panel frame fits the limiting groove, and the side panel is clamped in the first fixing part, completing the connection between the mesh and the side panel. When the first fixing part is opened, the first hydraulic rod is extended, the opening of the limit slot is enlarged, the clamping of the side plate by the first fixing part is released, and the side plate frame can be separated from the limit slot. Since the volume of the breeding net cage is large, the area of ​​the side plate and the mesh is also large, so the first hydraulic rod is used as the power source of the first fixing part to drive the first fixing part to clamp the side plate and the mesh together, so that the clamping power is more sufficient and the clamping effect is better.

[0009] Preferably, a second fixing part is provided on a guide rod in the mesh group, and the second fixing part includes a second fixing seat, a second hydraulic rod and a second fixing plate, the second fixing seat is C-shaped, the end of the second fixing plate is rotatably connected to the inner cavity of the second fixing seat, one side of the second fixing plate is fixedly connected to the guide rod, and the other side is rotatably connected to the second hydraulic rod, and the other end of the second hydraulic rod is rotatably connected to the inner cavity of the second fixing seat. The working principle of the second fixing part is the same as that of the first fixing part, and the second fixing part is driven by the second hydraulic rod to clamp the guide rod without the second fixing part, thereby completing the fixed connection of the two guide rods. After the mesh group is wrapped around the side plate, the provision of the second fixing part can increase the connection strength between the two driving meshes in the mesh group, thereby preventing the closed mesh box from being opened due to other reasons.

[0010] Preferably, there are two second fixing parts, which are respectively located at the two ends of the guide rod. The guide rod provided with the second fixing parts is also provided with a driven part and a connecting rod. The driven part is located between the two second fixing parts. The driven part includes a third fixing seat and a third fixing plate. The third fixing seat is C-shaped. The end of the third fixing plate is rotatably connected to the inner cavity of the third fixing seat. The connecting rod connects the second fixing plate and the third fixing plate to drive the second fixing plate and the third fixing plate to move synchronously. The third fixing plate is also fixedly connected to the guide rod. After the driven part is provided, more clamping points can be provided on the guide rod. Without adding an additional power source in advance, the connection strength of the two guide rods can be further increased, and the closed cage can be further prevented from being opened due to other reasons.

[0011] Preferably, rollers that can be inserted into the inner cavity of the electric slide rail are provided at both ends of the rotating shaft, and the rollers are rotatably connected to the rotating shaft. Specifically, telescopic rods are also provided at both ends of the rotating shaft, and the telescopic rods are fixedly connected to the rotating shaft. The rollers are located at one end of the telescopic rods away from the rotating shaft, and the rollers are rotatably connected to the telescopic rods. The rollers are connected to the rotating shaft through the telescopic rods, and the telescopic rods can extend the rollers into the inner cavity of the electric slide rail. When the mesh is unfolded, the rollers can extend into the inner cavity of the electric slide rail, so that the unfolded mesh has more support points on the electric slide rail, and the setting of the rollers can make it easier for the rotating shaft to slide in the electric slide rail.

[0012] Preferably, the side plate is a regular dodecagon, and there are twelve meshes, each of which corresponds to one side of the side plate. The dodecagonal side plate is closer to a circle, which is easier to decompose the impact of undercurrents below sea level and is easier to process. When the net cage is raised and unfolded on the floating platform, three meshes are unfolded on each side of the net group, at which time the unfolding area of ​​the net cage gap is the largest and the fishing efficiency is the highest.

[0013] Preferably, a universal joint coupling is provided at the driving end of the rotating mechanism, one end of the universal joint coupling is fixedly connected to the driving end of the rotating mechanism, and the other end is fixedly connected to the midpoint of the side plate. After the universal joint coupling is provided, the tilt angle of the net cage can be adjusted during the lifting process of the net cage, so that the net cage is tilted. After the net cage is tilted, the farmed fish inside it will accumulate on one side of the net cage. After the net cage is opened, the farmed fish accumulated in one place are easier to catch.

[0014] Preferably, the lifting mechanism includes a bracket, a connecting rope, a fixed pulley and a winch. The bracket and the winch are both fixedly connected to the floating platform. The fixed pulley is located at the top of the bracket and is slidably connected to the bracket. One end of the connecting rope is connected to the winch, and the other end is connected to the rotating mechanism by bypassing the fixed pulley. A counterweight is also provided on the connecting rope. The counterweight is detachably connected to the connecting rope. The counterweight and the net cage are respectively located on both sides of the fixed pulley. Reinforcing ribs are also provided between the bracket and the floating platform. When the net cage is raised, the winch retracts the connecting rope; when the net cage is lowered, the winch releases the connecting rope. A counterweight is also provided on the connecting rope, so that the winch can pull the net cage up with a smaller pulling force. Reinforcing ribs are provided on the bracket to prevent the bracket on the floating platform from tipping over.

[0015] Compared with the prior art, the utility model has the following beneficial effects: when the aquatic products inside the aquaculture net cage need to be taken out, the net on the side wall of the net cage can be unfolded and spread flat on the floating platform, and a gap sufficient for fishing is opened on the net cage, so that the staff can quickly take out the aquatic products in the net cage through the gap on the net cage, shortening the fishing time of farmed fish and avoiding the death of too many farmed fish due to the long fishing process. At the same time, the net can also be fully unfolded on the floating platform, and the working space is larger when cleaning the net on the net, which is more convenient for the staff to clean and replace the net.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0026] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0027] Example 1

[0028] like Figure 1-Figure 5 The figure shows an embodiment 1 of a breeding cage for catching and harvesting fish, comprising a floating platform 1, a lifting mechanism 2 fixedly connected to the floating platform 1, a rotating mechanism 3 fixedly connected to the driving end of the lifting mechanism 2, and a cage 4 connected to the driving end of the rotating mechanism 3. The floating platform 1 has a lifting port 101, through which the cage 4 can enter the sea. The cage 4 comprises a regular dodecagonal side plate 401 and a mesh group unfolded into a rectangle. The driving end of the rotating mechanism 3 is connected to the center of the side plate 401. The rotating mechanism 3 is a rotating motor. The side plate 401 constitutes two end faces of the cage 4, and the mesh group constitutes the side face of the cage 4. The mesh group includes twelve meshes 402 that are rotatably connected in sequence, each mesh 402 corresponds to an edge of the side plate 401, and two adjacent meshes 402 are connected by a rotating shaft 403. The end of the mesh 402 connected to the side plate 401 is provided with a first fixing part 5 for connecting to the frame of the side plate 401, and the first fixing part 5 can fix the mesh 402 and the side plate 401 together. The two meshes at both ends of the mesh group are driving meshes 421, and the end of the driving mesh 421 away from the rotating shaft 403 is provided with a guide rod 404, and the two ends of the guide rod 404 are telescopic rods, and the telescopic rod is provided with a ball head 405. The floating platform 1 is provided with an electric slide rail 6, and an electric slider 7 is slidably connected in the electric slide rail 6. The electric slider 7 is provided with a card slot 701, and the card slot 701 can be carded with the ball head 405. The floating platform 1 is also provided with a power mold base 8 electrically connected to the electric slider 7. The power mold base 8 provides power to the electric slider 7. A pulley 702 is provided at the bottom of the electric slider 7. The electric slider 7 slides in the electric slide rail 6 by driving the pulley 702 to rotate.

[0029] The working principle or working process of this embodiment is as follows: when catching the cultured fish in the culture cage 4, the lifting mechanism 2 drives the cage 4 located below the sea level to move upward until the cage 4 floats above the sea level, and then rotates the cage 4 so that the guide rod 404 on the cage 4 is the highest point of the cage 4 in the vertical direction. When the cage 4 floats above the water surface, it will pass through the lifting port 101 on the floating platform 1. At this time, the telescopic rods at both ends of the guide rod 404 are retracted, and the ball head 405 on the guide rod 404 is aligned with the slot 701 on the electric slider 7 after passing through the floating platform 1. Then the telescopic rod is extended, and the ball head 405 is inserted into the slot 701. At the same time, the lifting mechanism 2 continues to drive the cage 4 to rise. After the ball head 405 is inserted into the slot 701, the electric slider 7 slides in the electric slide rail 6 in the direction away from the cage 4, so that the driving mesh 421 has a tendency to unfold. At this time, the first fixing part 5 on the driving mesh 421 is opened, and the driving mesh 421 rotates on the rotating shaft 403 until the driving mesh 421 is unfolded on the floating platform 1. Similarly, the electric slider 7 continues to move to drive more meshes 402 to unfold on the floating platform 1, until three meshes 402 are evenly spread on the surface of the floating platform 1 on both sides of the lifting port 101. Figure 3 As shown, the farmed fish in the cage 4 can be caught through the unfolded part of the cage 4. When the farmed cage 4 is relocated, the lifting mechanism 2 drives the cage 4 to move downward, and the electric slider 7 also moves in the direction of the cage 4. At this time, the electric slider 7 drives the unfolded mesh 402 to re-contact the side of the side plate 401. When the mesh 402 is in contact with the side plate 401, the first fixing part 5 on the mesh 402 completes the connection between the mesh 402 and the side plate 401, so that the mesh 402 is fixed on the side plate 401 until all the meshes 402 are fixed on the side plate 401. At this time, the inner cavity of the cage 4 is in a closed state, as shown in FIG. Figure 1 Then the telescopic rod on the guide rod 404 contracts to drive the ball head 405 to disengage from the slot on the electric slider 7, and the lifting mechanism 2 continues to drive the net box 4 to descend, and the net box 4 sinks into the sea again, completing the relocation of the net box 4. When it is necessary to clean the nets on the mesh 402, the mesh 402 is fully unfolded on the floating platform 1, so that all the nets on the net box 4 can be effectively cleaned.

[0030] Beneficial effects of this embodiment: When the aquatic products inside the aquaculture net cage 4 in this solution need to be taken out, the mesh 402 on the side wall of the net cage 4 can be unfolded and spread flat on the floating platform 1, and a gap sufficient for fishing is opened on the net cage 4, so that the staff can quickly take out the aquatic products in the net cage 4 through the gap on the net cage 4, shortening the fishing time of farmed fish and avoiding the death of too many farmed fish due to the long fishing process. At the same time, the mesh 402 can also be fully unfolded on the floating platform 1, and the working space is larger when cleaning the net on the mesh 402, which is more convenient for the staff to clean and replace the net. The dodecagonal side plate 401 is closer to a circle, which is easier to decompose the impact of undercurrents below sea level and is easier to process.

[0031] Example 2

[0032] Embodiment 2 of a breeding cage convenient for catching and harvesting, as Figure 2 and Figure 6 As shown, based on Example 1, the structure of the cage 4 is further limited.

[0033] Specifically, the first fixed part 5 includes a first fixed seat 501, a first hydraulic rod 502 and a first fixed plate 503. The first fixed seat 501 is C-shaped. The end of the first fixed plate 503 is rotatably connected to the inner cavity of the first fixed seat 501. One side of the first fixed plate 503 is fixedly connected to the frame of the mesh 402, and the other side is rotatably connected to the first hydraulic rod 502. The other end of the first hydraulic rod 502 is rotatably connected to the inner cavity of the first fixed seat 501.

[0034] Specifically, a second fixing part 9 is provided on a guide rod 404 in the mesh group, and the second fixing part includes a second fixing seat, a second hydraulic rod and a second fixing plate. The second fixing seat is C-shaped, and the end of the second fixing plate is rotatably connected to the inner cavity of the second fixing seat. One side of the second fixing plate is fixedly connected to the guide rod 404, and the other side is rotatably connected to the second hydraulic rod. The other end of the second hydraulic rod is rotatably connected to the inner cavity of the second fixing seat.

[0035] Specifically, there are two second fixing parts 9 and they are respectively located at the two ends of the guide rod 404. The guide rod 404 provided with the second fixing part 9 is also provided with a driven part 10 and a connecting rod 11. The driven part 10 is located between the two second fixing parts 9. The driven part 10 includes a third fixed seat and a third fixed plate. The third fixed seat is C-shaped. The end of the third fixed plate is rotatably connected to the inner cavity of the third fixed seat. The connecting rod 11 connects the second fixed plate and the third fixed plate to drive the second fixed plate and the third fixed plate to move synchronously. The third fixed plate is also fixedly connected to the guide rod 404.

[0036] Specifically, telescopic rods are also provided at both ends of the rotating shaft 403, and the telescopic rods are fixedly connected to the rotating shaft 403. A roller 12 is provided on the end of the telescopic rod away from the rotating shaft 403. The roller 12 can be extended into the inner cavity of the electric slide rail 6. The roller 12 is connected to the rotating shaft 403 through the telescopic rod on the rotating shaft 403.

[0037] The working principle or working process of this embodiment is as follows: the extension and retraction of the first hydraulic rod 502 will drive the first fixed seat 501 to rotate on the mesh 402. When the first hydraulic rod 502 is extended and retracted until the first fixed plate 503 is perpendicular to the bottom surface of the first fixed seat 501, a limiting groove for accommodating the frame of the side plate 401 will be formed between the mesh 402 and the first fixed seat 501. After the frame of the side plate 401 is inserted into the limiting groove, the fixed connection between the side plate 401 and the mesh 402 can be completed. When the mesh 402 is connected to the side plate 401, the first hydraulic rod 502 is extended to enlarge the opening of the limiting groove. After the frame of the side plate 401 enters the inner cavity of the limiting groove, the first hydraulic rod 502 is contracted to reduce the limiting groove until the frame of the side plate 401 fits the limiting groove, and the side plate 401 is clamped in the first fixing part 5, completing the connection between the mesh 402 and the side plate 401. When the first fixing part 5 is opened, the hydraulic rod is extended, the opening of the limiting groove becomes larger, and the clamping of the first fixing part 5 on the side plate 401 is released, and the frame of the side plate 401 can be separated from the limiting groove. The working principle of the second fixing part 9 is the same as that of the first fixing part 5. The second hydraulic rod drives the second fixing part 9 to clamp the guide rod 404 without the second fixing part 9, and completes the fixed connection of the two guide rods 404. When the second fixing plate moves, the connecting rod 11 drives the third fixing plate to move, that is, the second fixing part 9 drives the driven part 10 to move through the connecting rod 11.

[0038] Beneficial effects of this embodiment: the first hydraulic rod 502 serves as the power source of the first fixed part 5, driving the first fixed part 5 to clamp the side plate 401 and the mesh 402 together, so that the clamping power is more sufficient and the clamping effect is better. The setting of the second fixed part 9 can increase the connection strength between the two driving meshes 421 in the mesh group, and prevent the closed mesh box 4 from being opened due to other reasons. The setting of the driven part 10 can add more clamping points on the guide rod 404, and can further increase the connection strength of the two guide rods 404 without adding additional power sources. When the mesh 402 is unfolded, the rotating shaft 403 connected to the mesh 402 can extend the roller 12 into the inner cavity of the electric slide rail 6 through the telescopic rod, so that the unfolded mesh 402 is provided with more support points on the electric slide rail 6, and the setting of the roller 12 can make it easier for the rotating shaft 403 to slide in the electric slide rail 6.

[0042] Specifically, the lifting mechanism 2 includes a bracket 201, a connecting rope 202, a fixed pulley 203 and a winch. The bracket 201 and the winch are fixedly connected to the floating platform 1. The fixed pulley 203 is located at the top of the bracket 201 and is slidably connected to the bracket 201. One end of the connecting rope 202 is connected to the winch, and the other end is connected to the rotating mechanism 3 by passing around the fixed pulley 203. A counterweight is also provided on the connecting rope 202, and the counterweight is detachably connected to the connecting rope 202. The counterweight and the net box 4 are respectively located on both sides of the fixed pulley 203. A reinforcing rib 204 is also provided between the bracket 201 and the floating platform 1.

[0043] Beneficial effects of this embodiment: after the universal joint coupling 13 is provided, the tilt angle of the net cage 4 can be adjusted during the lifting process of the net cage 4, so that the net cage 4 is tilted. After the net cage 4 is tilted, the farmed fish inside it will be piled up on one side of the net cage 4. After the net cage 4 is opened, the farmed fish piled up in one place are easier to catch. A counterweight block is provided on the connecting rope 202, so that the winch can pull the net cage 4 up with a smaller pulling force. A reinforcing rib 204 is provided on the bracket 201, which can prevent the bracket 201 on the floating platform 1 from tipping over.
